To @ZZ whoml it may concern:

Be it known that I, NrcoLAs VoGLnY, a citizen ofthe Republic of France, residing at Lyons, in said Republic, have invented a new and useful Improvement in GlassBeveliug Machines, of which the following is a specification, reference being` had to the accompanying drawings.

This invention relates to that class'of glassbeveling machines in which the glass, held in an inclined reciprocating frame, is presented to the discoid face of a rotarygrinding or polishing wheel, the shaft of which is horizontal and has imparted to it a regulated pressure in an axial direction.

The improvement consists in a novel con-l struction of the glass-holding frame and novel means of supporting, adjusting, and operating the same, and in novel means whereby the adjustment of the pressure on the shaft of the grinder is produced and regulated, as hereinf after described and claimed.

`Figure l represents a frontelevation of a machine illustrating -iny invention. Fig. 2 is an end view ofthe same, showing certain parts in section in the line x a of Fig. l. Fig. 3 is a front view, on a larger scale than Figs. l and 2, of a portion of the glassholding frame.-

Fig. 4 is a horizontal section of the said frame, corresponding with Fig. 3 in the line z z, Figs. l and 3.

-Similar letters ol' reference indicate corresponding parts in the several iigures.

The rotary grinder A is mounted on ahorizontal shaft supported in bearings in a fixed frame, l. Upon the same shaft is also placed a cone-pulley intended to vary the speed ofthe grinder, according to its nature, its di1nen sions, and the work to be performed. This rotaryfgrinder may be turned either to the right or to the left, as may be desired, and may receive water and sand from a funnel iixed above, but which is not represented in the annexed drawings, all the detritus falling into a trough, F.

The frame which contains the glass to be ground consists of two channel-irons, V, forming the sides ot the frame and held together by a plate, E, and two other plates, G, Fig. l, placed the tirst near the middle of the `height and the others at the upper and lower parts of said channel-irons. These plates have near one of their ends a slot of convenient length, for the purpose ot' enabling the frame to be adjusted to pieces of glass of different widths. This slot may have substituted for it a series of holes very close together, for the same purpose. The glass to be operated upon is held in this frame between two wooden gibs, H, in the upper part of the said frame, and two other wooden gibs, H', in the lower partthereof, all of the said gibs having grooves in their inner edges for the reception of the edges of the plates to be beveled, and the lower gibs having angular feet for the support of the lower edge ofthe plate. These gibs are of a width to fit the channels of the side pieces, V, of the frame, and each is furnished with a screw, K, which passes tances apart and screws into the gib. By the aid of these holes and screws the gibs may be secured at various heights in the frames, according` to the height of the glass to be beveled. Theside pieces, V, carry also each a roller, C, running on a horizontal bar, J, which rests in adj ustabie supports n n', to be presently described. The axles of these rollers receive hooks l), which are connected with two cords, I d,' which wind up, respectively, on rollers M N, Fig. l, which work in fixed bearings in the stationary framing of the machine, the said cords passing over or around guide-pulleys o', attached to the stationary framing of the machine. Two other rollers, I, attached to the side pieces, V, of the glassholding frame, roll against an adjustable horizontal bar, J which is supported in adjustable supports of, to be hereinafter described and by means of the rollers O and I the reciprocating movement of the glass-holding frame,produced by the said cords d d and rollers M/N, as will A third bar, J', supported in adjustable supports a', is provided to guide the frame, which may also be provided with rollers to run against that bar.

To provide for giving to the cord-rollers M N a movement in opposite directions alterthrough one of a ser'ies of holes, c, (see Fig.- 3,) provided in the side pieces at short dis be presently described, is rendered very easy.

IOO

lwhich works in iixed bearings, and which car- Y an upright shaft,S3, on the upper end of which nately to wind up and unwind the two cords I d d', for giving the slow reciprocating motion to the glass-holding frame, there is a shaft, p,

ries a pinion, p', which gears with pinions 191k, one on each roller. I The said shaft is also furnished with three pulleys, It, of which one is fast and the others loose; but as these are all of the same size only one of them is visible in Fig. 1. These pulleys are furnished with open and crossed driving-belts, so that by shipping lirst one and then the other belt tothe fast pulley and the other to one of the loose ones the rollers M N may both be turned in one or the other direction, but each always in the opposite way to the other,\for the purpose of winding up one of the cords d d and unwinding the other, and so producing the movement of the carriage. The shipping of the belts to change the direction of the carriage may be produced by the action of a tappet-arxn, O, attached to the glass-holding frame, (see Fig. 2,) upon a tappet, O, on the belt-shipping bar P. As these means of producing rotary motion in opposite directions are Well known and in common use it is thought unnecessary to further `illustrate or describe them.

v In order to provide for varying the operative length of the cords d d', as is necessary for varying the reciprocating movement of the glass-holding carriage, the rollers M N are so connected by couplings with their axles or with their pinions piip that they may be disengaged from the said axles or pinions by sliding them along the axles, and so permitted to be turned by hand for unwinding or winding up more of their cords.

In Fig. l there are represented levers which are employed to effect the above-mentioned disengagement and the necessary re-engagenient; but as such means of engaging and dis-V engaging wheels or rollers from their axles are well known and form no part of this invention it has not been thought necessary to make a special drawing to illustrate the con! nections of the said levers.

The rotary grinder A is pressed against the glass with a const-ant pressure by means of a spring, Rt, (see Fig. 2,) which is attached to the iixed framing at R', and which has attached to its free end R2 a pressure-screw which abuts against the rear end of the shaft a ofthe grinder. The pressure ofthe spring on the shaft is adj usted by means of a cam or eccentric, S, the axle of which` turns in fixed bearings, and to which is attached a worm-wheel, S', which gears with an endless screw, S2, on

is a worm-wheel, Z, which gears with an endless screw,X/, on a horizontal shaft, X2,which is arranged in fixed bearings above the grindershaft, and which is furnished with a handwheel,by theturning of which the cam S can be turned to adj ust the pressure of the spring R.

The adjustable supports n n n2, of whichv there are two for each of the bars J J J", are borne by screws m m m, one for each support, which fits its respective screw like a nut. rIhe said screws work in fixed bearings in the stationary framing of the machine, and are confined longitudinally in said bearings, so that by turning them by means of handwheels j j j, provided upon them for the purpose, they may be made to produce the necessary movements of the supports u a nz, for carrying the bars back and forth to adjust the inclination of the glassho1ding frame, according to the angle of the bevel to be produced thereon. u

Vhat I claim as my invention,and desire to secure by Letters Patent, is-

1. The combination, with a glass-holding frame for. supporting a plate in an inclined position and a rotary grinder having a horizontal shaft and a discoid face, ofaspring, R, for applying pressure endwise to the said shaft, a cam or eccentric, S, for adjusting said spring to vary its pressure, and mechanism, substantially as herein described, for turning the said cam, as and for the purpose herein set forth.

2. The glass-holding frame consisting ol' the channel-iron side pieces having holes c c, the plates E G, on which said side pieces are laterally adjustable, the gibs H and H,tted to the channels of the side pieces, and the screws K, passing through the holes c c and entering the gibs, all substantially as herein described.

3. The combination, with the glass-holding `frame furnished with rollers C, the supportl ing-bars JJ J, the adjustable supports n n 01?, for said bars, and the screws J J J", for carrying and adjusting said supports,substan` tiall y as herein described. i

4. The combination, with the inclined glasseholding frame and supporting-bars for the same, of the cords d d', the pulleys r r, `for guiding the said cords,the rollers M N,for winding and unwiuding the said cords, and means, substantially as herein described, for imparting to the said rollers rotary motion in opposite directions alternately, for producing a reciprocating motion of the said frame, all substantially as herein described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
